It has been reported that some patients have been misdiagnosed with Sarcoidosis, when in fact the correct diagnosis in their specific case was Rheumatoid Arthritis.
Rheumatoid arthritis is a form of arthritis that affects the lining of the joints causing painful swelling. This can lead to bone erosion and join deformity and the inflammation caused by this disease can lead to damage in other areas of the body. Symptoms include pain, stiffness, tenderness, loss of flexibility, tenderness, warmth and swelling in the joints. Rheumatoid arthritis can be misdiagnosed as osteoarthritis, lyme disease, lupus, fibromyalgia, psoriatic arthritis, and gout.
